Would someone be so kind to tell me where to find the Air conditioner drain tube on a 1999 quad cab SLT 2500 with the Cummins diesel.

Water is getting in the cab on the passenger side but does not appear to be a leak from the windshield or window/door. It only appears to get the carpet wet when I run the air. Laying under the truck I simply cannot find it.

Thank you, john72

If your drain hose is missing you can get a replacement at NAPA. They carry a selection of hoses that are bent 90 degrees. I believe the size is 5/8, but you can check out that it fits before you leave the store. That's were I got mine when the original "went missing".

Thanks Chris, don't know what I would do without you, except spend big bucks at the dealer. Thanks again john72

 

I extended my drain with some heater hose, ran it down and along the frame, had the wet carpet syndrome also, along with every other dodge ram owner.

After running the garden hose everywhere with a stipped interior to find even more leaks, I ended up replacing the rear slider with an aftermarket, and siliconing the 3rd brake light fixed all my leaks.

 

I honestly didnt know there WAS an OEM hose placed on that little nipple from the factory... Must have been the job one of those factory guys that was AWOL alot..
All the replies I ever got was that short nipple was all there was, and the little foam donut on the inside of the cab was all that sealed the exterior water from the inside. I just cut a piece of clear vinyl tubing (naturally curved)about 8-10" long and let it drain downwards.

I dont think they put the tube on the 99's. I just used some heater hose.
